Kensington Resources Ltd.: Supplemental Microdiamond Results for Fort a la Corne Kimberlite 122
5/11/2005 9:01:03 AM
VANCOUVER, British Columbia, May 11, 2005 (BUSINESS WIRE) -- Kensington Resources Ltd. (the "Company") (TSX VENTURE:KRT) announces supplemental microdiamonds results received from the operator, De Beers Canada Inc., for Kimberlite Body 122 of the Fort a la Corne Diamond Project in east-central Saskatchewan. Selected 2003 coreholes were re-sampled to provide additional material for diamond recoveries utilizing caustic dissolution methods. These results include several larger diamonds including one recovered on a 2 mm screen.
Additional kimberlite samples totaling 464 kg from eight 2003 coreholes located across the body were submitted for diamond recovery utilizing caustic dissolution methods at the Saskatchewan Research Council (SRC) in Saskatoon. The SRC recovered and reported diamonds down to a lower cutoff of 0.075 millimetres in size. A total of 269 additional microdiamonds were recovered for use in grade forecasting of specific kimberlite zones. Microdiamond recoveries were audited and individual stone sizes calculated by experts at the De Beers Kimberley Microdiamond Laboratory (KMDL) in South Africa. All recoveries reported here include stones with modeled sizes less than 74 microns in size in order to be directly comparable to 2003 results from the SRC that were reported for several kimberlite units.
Initial geological modeling of distinct kimberlite phases by De Beers, based on drill core from Kimberlite 122 shows the body is divisible into two main craters, and a subordinate third area based on relatively sparse information. Both craters are dominated by massive to graded beds of olivine/lapilli pyroclastic kimberlite (MPK-N and MPK-S) overlain by interbedded sediments, resedimented kimberlite, and kimberlite (UCSK-N and UCSK-S). The order of emplacement for the individual kimberlites and their contact relationships within, and between, the two main parts of body 122 are not fully understood at this time. See the Company's news release of May 21, 2004 for a more detailed summary of the 122 geology.
The average microdiamond abundance for all 122 samples from 2004 is 5.8 stones per 10 kg while the upper 122 North beds (UCSK-N) gave the best results with average microdiamond abundances of 8.3 stones per 10 kg. In general, the results for the North crater are comparable between 2003 and 2004, but a significant decrease in recovery was noted for both units in the South crater. There is no obvious reason for the difference in results between years for the same core, except that which is expected from the "nugget-effect", whereby there is irregular recovery of diamonds within small sample masses. Both 2003 and 2004 results will be combined by kimberlite unit to produce higher confidence grade forecasts. A summary of diamond recovery by kimberlite phase is shown in the table below and a full table of results by sieve category will be available on the Company's website at www.kensington-resources.com.
